Global research progress on mining wastewater treatment: …
Coal mining and gold mining have received more attention because of their higher demand in the business field. On the other hand, the terms "landfill mining" and "passive treatment" are rarely used and we can observe a pink color group in Fig. 4(a). However, this may change in the future depending on scientific advances.

Proposed Regulatory Framework for Coal Mining
Most effluent treatment at coal mining operations in Canada is done by conventional means, i.e., diversion, settling, and sedimentation, and the treated effluent is then discharged into the receiving environment. Effluent from coal processing operations can also be recycled. A general overview of coal mining operations

phosphorous removal to meet NPDES effluent limits. Effluent water from the 14 Mile Run facility used in this study contains 3-6 mg/l of phosphorus since the treatment system does not have a phosphorus limit. The effluent water was stored in acid washed brown glass bottles, and was characterized using methods outlined in Standard Methods (12).

Evaluation of ionic contribution to the toxicity of a coal-mine
Some water-treatment processes (e.g., pH modifications) discharge wastewaters of potentially adverse TDS into freshwater systems. Strong correlations between specific conductivity, a TDS surrogate, and several biotic indices in a previous study suggested that TDS caused by a coal-mine effluent was the primary stressor.
